An overview of Signaling System No.7

Abstract

In modern telecommunication networks, signaling constitutes the distinct control infrastructure that enables provision of ALL other services. The component of signaling systems that controls provision of services between the user and the network is the access signaling component, and the component that controls provision of services within the network, or between networks, is the network signaling component. There are international standards for both access signaling and network signaling protocols. From a network structure viewpoint, access signaling structures generally provide point-to-point connectivity between the user and a network node, while network signaling structures provide network-wide communication capability (directly or indirectly) between the nodes of the public network(s). Since the network signaling system acts as a traffic collectorldistributor for many access signaling tributaries, its functions are more complex, its structure more involved, and its performance more stringent. This paper provides an overview of modern network signaling systems based on the Signaling System No. 7 international standard.

Mechanism for reliable low latency communications in Computing Clusters

“…Cisco uses an implementation of RUDP in its Signaling Link Terminals. RUDP Version 0 is used to backhaul the Signaling System 7 protocols over IP signaling control networks while Version 1 is used for ISDN networks [10] [11]. The low latency provided by UDP makes it suitable for IPTV and VoIP applications since they require very high throughputs and are somewhat tolerant to low levels of packet losses [12].…”

Experiences in automating the testing of SS7 signalling transfer points

“…Signalling System 7 (SS7) [6] is used around the world to provide the signalling required for telephone communications. A core component of an SS7 network is the Signalling Transfer Point (STP).…”

Novel resource reservation schemes for optical burst switching

“…This is similar to the common channel signaling (CCS) that has been used to separate the call setup control and the voice transmissions paths in traditional telephone networks. CCS uses two-way reservation [13]. The source waits for the reservation acknowledgment before commencing communication.…”
